I've worked odd hours sometimes. Some things I loved, some things I didn't. I used to work a night shift at a deli. It was nice to do my shopping at 2 am when there were no crowds around, and to have the days free. OTOH, it was a real drag on my social life, since all my friends socialized in the evenings, while I was at work.

I sometimes work evenings and weekends, and I like the peace of a quiet office. But there are drawbacks. If the network goes down, there's no one to fix it. And the building is often physically uncomfortable, since they turn off the heat/air conditioning outside regular work hours. There are also security issues, like the superior with a drinking problem came in late in order to grope me, knowing I would be alone.
